Blog Post 1— The Vast Size and Scale of the Universe

A collection of many galaxies that shows the vastness of the universe Humans have never travelled outside of our solar system because we are technologically unable to do so. Yet the solar system is only a tiny fraction of our galaxy, the Milky Way, and the Milky Way Galaxy is only a fraction of the […] Continue reading

The Fermi Paradox

A possible solution to the Fermi Paradox? The Fermi Paradox attempts to answer the question about extraterrestrial life that so many humans have thought about for centuries. Enrico Fermi a physicist, in 1950, while discussing extraterrestrial life he began to wonder if aliens did in fact exist then how have they not expanded throughout the […] Continue reading

Blog #4 – Evidence for the Existence of Dark Matter

Dark Matter is a fascinating topic, yet we know so little about it. Regardless, a good amount of evidence exists that indicates dark matter is real. One pertains to the flatness of rotation curves for spiral galaxies at extended distances. The graph does not drop off, but rather, continues in (essentially) a flat rotation curve, […] Continue reading

James Webb Space Telescope Discovers “Impossible” Galaxies

I’m sure many of you are familiar with the James Webb Space Telescope: the successor to the Hubble Telescope and most powerful space telescope built to date. It was launched into space a little more than one year ago with the goal of observing the first galaxies and investigating our cosmic origin. In this short […] Continue reading

Gravitational Lensing!

In class, we’ve been diving into the world of gravity and light. We have covered Newton’s laws of motion and the effects of gravity in our universe. As well, we’ve explored how light behaves and travels through space. Now I want to introduce another intriguing topic that combines the two –gravitational lensing! Gravitational lensing occurs […] Continue reading

The Scale of the Universe and Us

     Reading the graphic in the textbook called “Our Cosmic Address”, I got a sense for the first time of how small of a planet we live on. Earth is a typical planet rotating by a typical star we call the Sun which is only one of billions of stars in the Milky Way which is […] Continue reading

The Fermi Paradox : Are We Alone?

The Fermi Paradox Picture The universe is magnificently huge, and hence should have countless opportunities for life to develop, but that then begs the question, where are all the aliens? Due to the expansion of the universe being faster than the speed of life, there may be life throughout many galaxies, or even most of …
